For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, ...

(PhysOrg.com) -- Under a microscope they look like tiny pie charts or colorful candy canes: A team led by Joerg Lahann at the University of Michigan has been able to produce micrometer-wide discs and elongated rods precisely ...

Researchers at the University of California, San Diego have developed a novel method of disguising nanoparticles as red blood cells, which will enable them to evade the body's immune system and deliver cancer-fighting drugs ...

Jose Ramon Sarasua and Aitor Larrañaga, researchers in the materials engineering department of the UPV/EHU-University of the Basque Country, have been studying new materials or implants that are of interest ...

There is a growing need for biocompatible photonic components for biomedical applications - from in vivo glucose monitoring to detecting harmful viruses or the telltale markers of Alzheimer's. Optical waveguides are of ...

Biomaterials are crucial to the development of many modern medical devices and products including biodegradable sutures, bone screws, pins, rods and plates, and scaffolds for regenerating bone, cartilage ...

Every second counts when treating a traumatic injury. While our bodies are built to quickly stem bleeding from everyday nicks and cuts, major trauma -- whether sustained on the battlefield or in a car accident ...

(PhysOrg.com) -- A research group reported recently in the Proceedings of the National Academy of Sciences that they have engineered nanoparticles to help block a protein process that takes place in tumors, making the tu ...

A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated ...
